The accident happened on a downhill stretch of narrow North Mason Road when the rescue truck, moving about 5 mph, struck the parked vehicle around 8:15 a.m., he said. The rescue truck suffered no damage, but bent the pickup's bumper and a section of a rear body panel.

The initial accident was in the same area involving a different pickup truck that struck a tree, causing extensive damage, Corey said. He said that appeared to be weather-related as well.

No one was injured in either accident.

Brookline Police said no one at the station had information regarding the fire truck mishap.
